HO300-226 - HI RAM BASE ONLY LS1 LS2 LS6

Manifold Base Only Suit Carburettor Application

Part Number: HO300-226

The Holley GM LS1/LS2/LS6 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS1/LS2/LS6 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!
The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems.
Runner length and the tapered cross–section designed to perform well for a wide range of engine configurations
EFI fuel rails are machined for -8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.
Cast aluminium construction.
Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000–8000+RPM.
Features:
Port Size - 2.49" Height x 1.21" Wide
Mounting Flange Gasket Type - Standard LS3 Molded O-Ring
Plenum Top Gasket Type - 3/32" Round O-ring Cord
Runner Length - 6.58", As-Cast Runner Cross-Sectional Area - Tapered 4.25 in sq to 2.53 in sq

Durable and solid construction!
Size: Extra Large Size 4, Color: Rainbow, Size: Extra Large Size 4, Color: Rainbow
Colorful, easy to inflate, durable. Arrived quickly and excellent condition. My dog really enjoys her play time with it. I have a mixed breed border collie and she has been giving this ball a run for the money! My dog is 30 lb, we ordered the extra large size.

Dogs only toy that has not broken.
Size: Extra Large Size 4, Color: Rainbow
I've ordered them in 6, 7, and 8 inches I think. She is an aggressive chewer who had destroyed every toy I've given her. But not these! She has chewed off every strap which I've promptly taken from her to avoid her eating them. But the ball itself is chew resistant! I use the small 6" one to play around inside with her and the larger ones to play outside. My puppy absolutely loves playing "soccer" with these. Worth the money IMO.

Pup loves this!
Size: 6 Inch, Color: Red
This soccer ball is so cute. My dog loves to play with these. The straps are durable, easy to pump up (they come with a pump), good value for the money since they tend to last awhile, at least for us. The straps are durable but could be an issue if your dog is an aggressive chewer. They stay pumped up for quite awhile and just need to be topped off once in awhile to keep the bounce there. We keep them outside even in the winter and they do just fine. HIghly recommend as a good play toy.

Great Ball
Size: 6 Inch, Color: Red
Our Little Goldendoodle Loves this ball & I like that it has so many straps to grab so I'm not getting the slimy part. It does not come already inflated so make sure you or a neighbor have an air compressor to blow it up because even though it came with a little pump I can't imagine how many weeks I'd have been pumping that without noticing any difference.
